Change Details

Some wikis serve as "backend", and gadgets make write API requests against them without sending the user there. E.g. one might edit an infobox with [[ https://ru.wikipedia.org/wiki/%D0%92%D0%B8%D0%BA%D0%B8%D0%BF%D0%B5%D0%B4%D0%B8%D1%8F:WE-Framework | WE-Framework ]] which makes a Wikidata edit in the background. There are similar use cases for Commons file uploads. We should make sure this works even if the user never visited that wiki before (and thus has no local user account there and/or is not logged in).
